Frequently Asked Questions — JUP Flash Loan

What is a JUP flash loan?▼

A JUP flash loan lets you borrow Jupiter (JUP) with zero collateral in a single Solana transaction. You receive the full amount, execute your strategy (arbitrage, liquidation, collateral swap), and repay — all atomically. If repayment fails, the entire transaction reverts.

How much does a JUP flash loan cost?▼

The current fee for a JUP flash loan is 0.03%. This is the flat VAEA protocol fee — no swap costs since JUP is borrowed directly from lending protocols.

How much JUP can I borrow?▼

You can currently borrow large amounts of JUP. Available liquidity is pulled from Solana lending protocols and updated every 10 seconds. Check the dashboard for real-time availability.

What is the difference between direct and synthetic flash loans?▼

Direct flash loans borrow tokens directly from lending protocols (Marginfi, Kamino, Save) at a fixed 0.03% fee. Synthetic flash loans borrow a base token (SOL/USDC) and swap to your target token via Sanctum or Jupiter, with fees that vary based on market liquidity.

Why is JUP a direct route token?▼

Jupiter has deep liquidity in Solana lending protocols like Marginfi and Kamino, so VAEA can borrow it directly without going through a swap. This gives you the lowest possible fee (0.03%) and fastest execution.

Which SDKs support JUP flash loans?▼

VAEA Flash supports JUP in all three SDKs: TypeScript (npm i @vaea/flash), Rust (cargo add vaea-flash-sdk), and Python (pip install vaea-flash). All SDKs include simulation, fee estimation, and execute functions.

Is it safe to use JUP flash loans?▼

Yes. Flash loans are atomic — the entire transaction succeeds or reverts. You never lose funds because if the repayment fails, Solana rolls back everything. VAEA's on-chain program verifies repayment before the transaction finalizes.
